Freshness! Help Some Advise.

Just wondering ..... If I have a cake for Sat. delivery is it to early to start on Wed. or Thurs. Just wondering if it will affect freshness. I made the cakes a few days ago, froze them. I am thawing them out today and would like to ice with BC and then cover them in fondant. I am assuming that they should be OK as the fondant usually keeps the freshness in.

Thanks so much! I usually do the same, bake on Wed, ice and cover on Thurs and Decor on Fri. But I am actually icing and covering today, just want to be safe, don't want to compromise freshness and taste. I have 4 detailed cakes for this Sat and I want to make sure I will be on time and actually get some sleep. LOL
